c.
jennifer's husband was a carrier of the allele for the disease, and jennifer was not.

A

Explanation: Jennifer did not get it because it is not always a 100% that you will get the disease you can become a carrier though if you do not get it. Which is what happened to her, the child got it because the higher chance that had it chances were very high and through chance actually got it. Which is you want to look at this it can kinda explain.

Jennifer's baby brother: 78% Chance to get it, 56% Chance to turn into a carrier

Jennifer herself: 67% Chance to get it, 89% Chance to turn into a carrier

Jennifer's husband: I wouldn't know his chance but only estimate it. 45% Chance to get it, 59% Chance to turn into a carrier.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
